Title: Rotary kiln shell temperature scanning system
IPC: G01J5/00
Filed: 1961-10-23
Abstract: 917,343. Photo-electric temperature measurement apparatus. LEEDS & NORTHRUP CO. Oct. 23, 1961 [Nov. 15, 1960], No. 37932/61. Class 40 (3). Apparatus for measuring the temperature of a rotary kiln to determine the position of hot spots comprises a radiant energy detector oscillating about a fixed axis and driven by a reversible motor, a control switch operated during each revolution of the kiln to move the detector through a fraction of its scanning cycle and a pair of limit switches each reversing the direction of scan when the detector reaches the end of its oscillatory movement. In the arrangement shown the infra-red detector 11 oscillates through an angle of 90 degrees to scan a distance X along the periphery of the rotating kiln 13. For each revolution of the kiln 13 a control switch operates to move the detector through 3¢ degrees of the scanning angle. When the distance X has been scanned a limit switch operates to reverse the motor drive and return the detector quickly to its starting position. The second limit switch then operates and the cycle is repeated. If a hot spot is detected an alarm sounds and detector and the kiln are automatically stopped. The radiant output from the detector is also recorded, the control circuit (Fig. 2, not shown) incorporates electromagnetic relays. Specifications 692,116 and 696,604 are referred to.

Filed: 1972-08-16
Abstract: 1430938 Flame-retardant acrylic filaments COURTAULDS Ltd 15 Aug 1973 [16 Aug 1972] 38179/72 Heading C3P Acrylic filaments have distributed therein, as a flame retardant, a liquid brominated diphenyl ether which is usually present as a mixture of brominated derivatives (mainly as pentabrominated isomers). The filaments are derived from acrylonitrile polymers which may contain up to 25% by weight of units of one or more comonomers, e.g. methyl acrylate and itaconic acid. The flame retardant is suitably incorporated into the spinning dope (the solvent of which is, for example, aqueous sodium thiocyanate) from which the filaments are obtained; in such procedure the flame retardant is advantageously diluted with an inert diluent, e.g. a chlorinated paraffinic hydrocarbon.

Abstract: 966,942. Stuffing-box substitutes. DOMINION ENGINEERING WORKS Ltd. Oct. 22, 1962, No. 39896/62. Heading F2B. The rotatable agitator shaft 11 of a mixer is sealed where it extends through an opening 14 in an end wall 12 of the pressurized mixing chamber by means of a sealing member 16 which is urged into engagement with the shaft by a member 20 operably connected to sealing pressure control means whereby application of pressure on the member 20 is varied in response to variations of the pressure in the mixing chamber. The mixing chamber is provided with two agitators and is fed through a hopper with the substance to be mixed, the latter being compressed in the chamber by a vertical fluid-operated hammer. The member 20 associated with each shaft 11 consists of a forked lever pivotable on a stud 21 and provided at the ends of its arms 23 with studs 24 which press against the sealing member 16 through a gland ring 15 and backing member 17. At its other end the lever 20 is provided with a dome-shaped chamber 28 bounded on one side by a flexible diaphragm 29 secured at its centre to a rod 33 engaging a recessed button 34 in a cavity of the mixer housing. Each chamber 28 is connected by means of flexible pipes 41 to a fluid pipe line system which incorporates a number of control valves by means of which fluid is supplied to operate the substance-compressing hammer and fluid pressure is increased or reduced simultaneously in all chambers 28 depending whether the hammer is being applied to, or raised from, the substance in the mixing chamber. Increased pressure in each chamber 28 causes flexing of the diaphragm which causes tilting of the lever about its pivot thereby increasing the pressure supplied by the studs 24 on the sealing member 16.

Abstract: 1324398 Photographic cameras EASTMAN KODAK CO 20 Aug 1970 [20 Aug 1969] 40162/70 Heading G2A A single lens reflex camera has a holder 4a for receiving a percussion ignitable flash unit, e.g. a flash cube, and for locating a striker 26a thereof in a firing position, the camera also being provided with a shutter having a rotatable control shaft 22a carrying a pinion 22, and with an actuating bar 6 which is connected to the shaft 22a for movement into the firing position in synchronism with shutter operation. When no flash unit is present Fig. 1 (not shown), a latch member (5) is held by a spring (5a) so as to engage a projection (6c) of the bar (6) to prevent it rising. When the shutter is actuated, movement of the shaft 22a is transmitted to a three arm lever 16 which actuates the shutter 2 and raises the mirror 20. Insertion of a flash unit depresses a member 4, thus rotating the latch 5 and allowing the bar 6 to rise until an end thereof engages, but does not release, the striker 26a. As the shutter is actuated, a cam 16a on an arm 16d of the lever engages a projection 6a of the bar to raise the latter and release the striker to fire the flash-lamp. The movement also results in a flag 10c becoming visible in the camera viewfinder.

A moving steel band 1 is cut by a toothed cutter 4 to form wires 5 and grooves in the band 1. The ridges between the grooves are severed by a flat cutter 7 to again give the band 1 a flat surface and form wires 8 which are combined at a roller 10 with the wires 5 to form a group 11. By arranging several pairs of toothed and flat cutters along the path of the band 1 (Fig. 1b, not shown), several groups 11 of wires can be formed into a bundle of parallel wires. The mass 16 is formed by stacking layers of the wires at 90 degrees to each other or folding a layer into zig-zag formation or into a helical coil (Figs. 2- 4, not shown). The mass is compressed in a die to 50% of its original volume, normalized at 650‹ C. in H 2 , further compressed and sintered at 1100‹ C. The sintered mass may be turned on a lathe to the required shape. The housing 17 of the regenerator has metal gauze ends 18.

Filed: 1970-08-26
Abstract: 1322596 Function generator GENERAL ELECTRIC CO 26 Aug 1970 [29 Sept 1969] 41138/70 Heading G4H [Also in Division H2] A polyphase sinusoidal current is generated by feeding pulses through a digital to analogue converter where they are weighted to form the sine wave. Each sine wave of the polyphase supply is generated by feeding clock pulses to a counter and decoder 21 which produces an output on one of 36 lines, 27, in sequence. This divides a period of the sine wave into 36 equal segments of 10 degrees. The signals are fed to digital to analogue converter 23 to produce weighted output pulses, the signals being used singly, and in selected combinations, so that the number of output steps exceeds the number of constituent signals. The digital to analogue converter employs precision-weighted resistances 167, 197, etc., Figs. 7, arranged in parallel and switched by diodes 159, 171, 189, 201, &c. Each phase employs 2 digital to analogue converters, one for the positive half of the sine wave and the other for the negative half of the sine wave. If a three phase output is required there are thus three pairs of digital to analogue converters. Signals from the counter 21 are fed to the digital to analogue converters for the separate phases in appropriate order to ensure the correct phase relationship between the phases. The phase order may be reversed by reversing the direction of counter 21.
